AR (Abrasion Resistant) hlaustands raws li lub caj qaum ntawm siab - coj ib puag ncig kev lag luam- los ntawm kev tsuas, kev tsim kho, thiab kev tsim khoom mus rau kev tuav cov khoom.
Nws ua lub luag haujlwm tseem ceeb hauv ntau yam kev ua haujlwm uas cuam tshuam nrog kev cuam tshuam loj thiab kev sib txhuam zawv zawg, nrog rau nws cov txiaj ntsig tseem ceeb cuam tshuam txog kev siv cov cuab yeej siv txuas ntxiv, txo cov nqi khiav lag luam thiab kev saib xyuas, thiab ua kom muaj kev tsim khoom tas mus li.
AR hnav-cov qib resistant steel feem ntau yog pawg los ntawm hardness-zoo li AR400, AR500, thiab AR600. Tus lej siab dua, qhov nyuaj ntawm cov hlau nto.
Cov qib no kuj txawv ntawm peb txoj hauv kev: lawv hnyav npaum li cas, cov hlau uas lawv sib xyaw nrog (xws li manganese lossis npib tsib xee), thiab lawv tuaj yeem ua tuab npaum li cas. Cov kev sib txawv no ncaj qha cuam tshuam rau kev siv ntawm kev lag luam.
Xaiv qhov tsis ncaj ncees lawm qib AR tsis yog qhov yuam kev me me -nws yog qhov pheej hmoo kim. Thaum ntsib nrog cov xwm txheej sib txawv, thaum qhov cuam tshuam rau qib yuav tsum tau txais, tab sis koj xaiv cov zawv zawg hnav, cov khoom hnav sai dhau, cov khoom siv kaw tsis tau xav txog (nqi ntau txhiab ib teev hauv kev tsim khoom ploj), kev saib xyuas / hloov cov nqi nce, thiab koj cov khoom siv tsis ntev li ntev tau. Hauv qhov xwm txheej tsis zoo, nws tuaj yeem ua rau muaj teeb meem kev nyab xeeb- tig qhov kev xaiv "pheej yig" mus rau qhov teeb meem loj nyiaj txiag thiab kev ua haujlwm.
Kab lus no yuav qhia txog qhov nyuaj los coj koj AR steel xaiv
- Impact Hnav:thaum cov cuab yeej ntsib tam sim ntawd, siab - quab yuam kev sib tsoo (xws li, pob zeb cuam tshuam, cov khoom sib tsoo), nws qhia tau hais tias yog dents, tawg, thiab cov khoom txav. AR400 thiab AR450 sawv tawm raws li cov kev xaiv zoo tshaj plaws: AR400 muab qhov pov thawj qhov sib npaug ntawmcuam tshuam toughnessthiab hardness (370-430 BHN), ua rau nws resilient rau rov cuam tshuam thaum tswj kev hnav tsis kam. Nws cov ductility siab tso cai rau nws nqus lub zog hnyav los ntawm kev sib tsoo yam tsis muajbrittle puas. AR450 (430-490 BHN) nce hardness me ntsis yam tsis muaj kev cuam tshuam cov tawv nqaij, haum rau cov ntawv thov uas hnyav dua. Ib rooj plaub hauv cov ntsiab lus: mine crusher liners siv AR400 kawg 3x ntev dua li cov qauv hlau, zam kev poob qis los ntawm kev tawg ntxov ntxov. Pob tseg tsheb txaj lined nrog AR450 lis jagged pob zeb loads yam tsis muaj denting, txo txij nkawm ncua sij hawm los ntawm 50%.
- Sliding Hnav:Nruam, qis-rau- nruab nrab quab yuam kev sib txhuam (xws li, cov khoom zawv zawg ntawm qhov chaw, conveyor txav), thiab nws pom nyob rau hauv daim ntawv ntawm deg abrasion, thinning, thiab du degradation. AR500 (470–530 BHN) thiab AR600 (570–630 BHN) yog engineered rau qhov kev sib tw tiag tiag: lawv cov ultra- tawv tawv tiv thaiv gouging thiab sib tsoo, txawm nyob rau hauv tas li zawv zawg siab. AR500 yog lub tshuab ua haujlwm rau feem ntau cov ntaub ntawv zawv zawg, muab qhov sib npaug ntawm qhov nyuaj thiab ua haujlwm tau zoo- tseem ceeb rau kev tsim cov chutes lossis cov hniav. AR600, nrog nws cov tawv tawv dua, ua tau zoo hauv cov xwm txheej zawv zawg hnyav xws li siab -abrasive ntxhia ua los yog cov cement cog hoppers, qhov twg cov qauv qib hnav nyias hauv lub hlis. Piv txwv li, conveyor chutes lined nrog AR500 pom hnav tus nqi 70% qis dua AR400, thaum AR600 txuas ntxiv lub neej ntawm scraper hniav hauv asphalt sib xyaw cov nroj tsuag mus txog 2 xyoos. Nco tseg: Cov qhab nia no muaj qis dua, yog li lawv yuav tsum tau zam nyob rau hauv qhov chaw siab - cuam tshuam los tiv thaiv kev puas tsuaj.
Txawm li cas los xij, hauv peb txoj haujlwm ua haujlwm, kuj tseem muaj qhov tshwj xeeb hauv kev sib txuas ob qho tib si cuam tshuam thiab swb rog ua rau muaj kev sib tw loj tshaj plaws. Cov kev daws teeb meem nyob rau hauv cov qib optimized rau ob qho kev ua tau zoo: AR450 thiab AR500 tawm tsam qhov kev sib npaug, muab qhov muaj zog txaus los tswj cov kev cuam tshuam qee zaus thaum tuav lub hardness xav tau rau zawv zawg hnav. AR450's nruab nrab-ntau hardness (430–490 BHN) thiab ductility zoo ua rau nws muaj ntau yam rau lub teeb-rau- nruab nrab hybrid loads, thaum AR500 (470–530 BHN) ua raws li ib tug ntau yam workhorse, tuav griding txaus ntshai thaum muaj kev kub ntxhov cuam tshuam. Rau cov xwm txheej sib txawv heev, cov tswv yim txo qis txhim kho kev ua tau zoo: kev kho deg zoo li hardfacing ntxiv hnav- txheej tiv thaiv rau tawv AR400 substrates, sib txuas cov kev cuam tshuam nrog kev tiv thaiv zawv zawg. Composite AR steel-txheej nrog siab-hardness thiab siab-toughness alloys- xa cov kev ua tau zoo rau cov ntawv thov xws li hybrid conveyor siv lossis cov khoom siv ore sorting, outperforming single-qib steel los ntawm 40% nyob rau hauv lub neej ntev.
Tom qab ua kev soj ntsuam thiab cov khoom lag luam kawm, yuav ua li cas xaiv cov qib kom raug thaum lub sijhawm ua haujlwm,
Ntsuam xyuas Wear Environment-Qhiacuam tshuam (kawg / dents) los yog zawv zawg (cov khaub ncaws hnav) ntawm kev kuaj xyuas; ntsuas qhov cuam tshuam quab yuam, zawv zawg ceev, thiab cov khoom abrasiveness.
Ntsuas Qib-Cross-reference BHN (hardness) thiab Charpy (toughness) nrog kev xav tau; cia siab rau cov chaw tsim khoom datasheets kom raug.
Secondary Factors- Account rau qhov chaw huab cua. Piv txwv li, nyob rau hauv sub- xoom kub, AR400 qhov qis dua - qhov kub thiab txias ua kom ntseeg tau tias cov qib nyuaj yuav ua tsis tiav.
Koj kuj koom tes nrog cov neeg muag khoom xws liPromisteelrau cov tswv yim tshaj lij.
Match AR qib rau hnav hom: Impact (AR400 / AR450), zawv zawg (AR500 / AR600), lossis hybrid (AR450 / AR500). Kev xaiv cov tswv yim txhim kho kev ua tau zoo thiab txiav tag nrho cov nqi.
Xaiv txoj cai Abrasion Resistant (AR) qib steel tsis yog ib qho kev nthuav dav xwb - nws yog ib qho kev txiav txim siab los tiv thaiv koj cov kab hauv qab. Los ntawm kev sib piv cov qib AR tshwj xeeb rau koj qhov chaw hnav khaub ncaws-txawm tias nws yog qhov cuam tshuam loj ntawm AR400 / AR450 lossis qhov zawv zawg qhov siab ntawm AR500 / AR600-koj tuaj yeem txuas ntxiv cov cuab yeej siv lub neej thiab txo cov nqi kho tsis tau xav txog.
Tsis txhob cia cov hlau tsis raug tso tseg koj cov khoom. Koom tes nrog cov kws tshaj lij xws li Promisteel kom tau txais cov kws tshaj lij kev soj ntsuam thiab qib siab - cov ntaub ntawv ua tau zoo raws li koj qhov kev lag luam nyuaj tshaj plaws. Ua lag luam nyob rau hauv durability hnub no los xyuas kom meej tas mus li, tus nqi- ua tau zoo tag kis.
FAQ
AR500 puas tuaj yeem siv rau hauv siab -ib puag ncig cuam tshuam?
AR500 yog engineered rau huab zawv zawg hnav thiab siab hardness. Txawm li cas los xij, vim nws qhov qis dua, nws yuav tsum tau zam nyob rau hauv qhov siab - cuam tshuam ib puag ncig kom tiv thaiv nkig tawg thiab tawg ntxov ntxov. Rau hybrid ib puag ncig, AR450 feem ntau yog ib qho kev cuam tshuam zoo dua.
Dab tsi yog qhov zoo tshaj plaws AR steel rau qis-kub mining?
Nyob rau hauv huab cua txias, hlau tuaj yeem ua nkig. AR400 yog qhov kev xaiv zoo tshaj plaws rau sub-zero mining operations vim nws muaj pov thawj qhov sib npaug ntawm ductility thiab hardness, tso cai rau nws tswj nws cov tawv thiab tiv thaiv tawg txawm nyob rau hauv siab - quab yuam cuam tshuam nyob rau hauv khov tej yam kev mob.
Yuav ua li cas AR steel txo - cov nqi ua haujlwm ntev?
Los ntawm kev sib piv cov qhab nia raug rau hom hnav, AR steel txuas ntxiv cov cuab yeej kev pab cuam lub neej zoo heev -piv txwv li, AR500 tuaj yeem txo tus nqi thauj khoom chute los ntawm 70% piv rau AR400. Qhov no txo qis kev tu ncua ncua sij hawm thiab tiv thaiv cov khoom siv tsis txaus siab kaw, ua kom cov khoom siv tas mus li thiab ROI.
